MarginMail vs Canary Mail: two takes on private AI email
Short answer: Canary Mail is a cross-platform mail app for every major provider, with on-device prioritization, cloud AI for writing and summaries, and PGP encryption on its top plan, from free to $100 a year. MarginMail is a native Mac app for Gmail and Google Workspace with no MarginMail server, AI on your Mac or through your own Claude, a calendar built in, and people pages. MarginMail never sends read receipts. It’s free during its beta.
